Question

Hi,

I have activated WIFI 2.4 GHz as a client to a wireless network. When I then goes to Failover, I get this error under the wan-network:

500 Internal Server Error

Sorry, the server encountered an unexpected error.

Failed to execute cbi dispatcher target for entry '/admin/network/mwan'.
The called action terminated with an exception:

Hello.

I tried to reproduce what you described and didn't find a similar error.

In testing used the latest firmware. If you are using an older version than the latest, please upgrade.

You can find her at this link:

https://wiki.teltonika-networks.com/view/RUTX11_Firmware_Downloads

To update go to the tab System->Firmware->Update firmware

Description link:

If issue persists, download troubleshoot file from your device and send me via PM.

Go to the tab: System->Administration->Troubleshoot

Kind regards.

Hi, tnx for reply. Unfortunately I have already tried this before I posted this.

PS: I'm waiting for a second router, I will try this WIFI setup on this one too. I'm not sure if it's problem with the router or if it's something I do wrong.

Hi again, I have now tryed another unit - and this one work... Have done the same thing on both devices, and unit 1 have the same problem and unit 2 work... Luckily it's not a problem that it work just on one unit - but it's a strange problem anyway.

Hello.

Did you try to update the latest firmware of the device without saving all the settings?

If not, do it and test again.

If issue persists, download troubleshoot file from your device and send me via Private Message.

Regards.
